To all whom it may concern:

Be it known that I, ROY CHESTER BLAOK- MAN, citizen of the UnitedStates, residing at Vest Park, in the county of Ouyahoga and State ofOhio, have invented certain new and useful Improvements in Attachmentsfor MotorCycles, of which the following is a specification.

This invention is a combination back, rear seat, and luggage carrierparticularly adapted and intended for use on motor bicycles.

Theobject of the invention is to provide a device which can beused as arear or auxiliary seat, or as a back for the ordinary seat, or as aluggage carrier, on a motorcycle, as will more fully appear from thefollowing description and the accompanying drawings.

In the drawings Figure 1 is a side elevation of the device. Fig. 2 is arear end view. Fig. 3 is an inverted bottom plan view. In these viewsthe device is shown as a seat. Figs. 1 and 5 are side and rearelevations showing the seat in raised position. Fig. 6 is a top view ofthe carrier, with the seat removed. Figs. 7 8, are respectively side andend views of a modification, the seat being down. Fig. 9 is a side viewof the modification, with the seat raised to form a back.

Referring specifically to the drawings, 1 indicates the frame of therear seat or back, with a pad 2 thereon, and metal plates 3 fastened tothe underside of the frame 1. This is hinged at its front end, asindicated at 4:, to the luggage carrier frame 5 which is relativelyfixed and is supported by uprights 13 and braces 10 at its oppositesides, the uprights 13 being attachable to the aXle of the rear wheel,by means of holes in the uprights provided for that purpose, and saiduprights may be bent out at the lower ends thereof to form foot rests.The upper ends of the braces 10 are connected by a cross piece 1Ofastened to the underside of the carrier frame 5, which has cross strapsor slats 21 to support a load.

The plates 3 have extended edges which form guides for slides 6 whichembrace the same and are slidable back and forth thereon, these slidesbeing connected to angular radius bars 8 which are pivoted at 14 to theuprights 13 and arranged to swing up and down with the seat 2. Springs 7are coiled around the upstanding ends of the bars 8 and serve to cushionthe seat. Braclc et-s 11, fastened to the braces 10, and cushioned byrubber blocks 12, form stops for the bars 8, to support the seat inhorizontal position, and guides 9, depending from opposite sides of thecarrier frame 5, serve to guide and hold the arms 8 in proper positionon said stops.

A plate 22 is connected at its rear end to the top or upper cross pieceof the uprights 13, and is adapted for attachment at its front end tothe rear fork of the motor cycle, directly under the ordinary seat (notshown).

WV hen desired the seat may be swung up as shown in Fig. 4, and issupported in such position by means of a pair of deteut plates 17 and 18which are pivoted at 19 to the frame 5 and are connected at their innerends by a pivot 20. Handles 15 and 16 project from the plates 17 and 18,and notches 17 at the outer ends of said plates 17 and 18 are adapted tocatch and engage the arms 8 when the seat is swung up, and a spring 25acts to hold them so engaged. The front bar of the carrier is indicatedat 24 (Fig. 6) to which the hinges 1 are attached.

In the use of the device the seat may be swung up or down as desired. Inthe latter position it is supported at the front end by the hinges andat the rear end by the springs 7 and arms 8, the latter resting on thebrackets 11, and in this position may be used as an auxiliary seat for asecond person to ride on the machine. When swung up, as shown in Figs.4: and 5, the arms 8 swing upwardly and forwardly and when in properupright position snap into the notches 17 at the outer ends of theplates 17 and 18, the spring 25 yielding to permit this movement, andthe seat will thus be so held to form a back to support the rider in theordinary saddle of the machine. And in this position the carrier 5 isadaptedvto receive apackage or other load which may be fastened thereonby any suitable means.

In the modified form shown in Figs. 7, 8 and 9 different means areprovided for supporting the seat and for raising and lowering the same.In this construction, an arched frame 30 is provided, attached at itslower ends to the carrier frame 5, and this piece, in connection withthe uprights 13, supports a pair of bars 29 to the front ends of whichare hinged, at 32, the front ends of leaf springs 31, on the rear endsof which are mounted the frame 20 of the seat 2. Straps 27 are fastenedto the front ends of the springs, on the underside thereof, and formguides for the ends of a crank 28 which turns in hinge or bearing pieces26 fastened to the arch connecting the uprights 13, and this crank isextended at one end to form a lever handle 15 which may be raised orlowered to swing the seat 2 up or down. The springs 31 are thus hung orsupported by the hinge 32 and the crank 28 and so the rear ends of saidsprings are free to vibrate or yield to cushion the seat 2. By swingingthe handle 15 forwardly the ends of the crank 28 slide down in theguides 27 and the seat drops to horizontal position. By swinging up thehandle 15 the seatis raised as shown in Fig. 9, the ends of the crank 28sliding to the upper ends of the guides 27, and said ends are located toform stops slightly beyond the center, so that the back is locked inraised position and will not fall down under pressure. hen the seat isso raised it forms a back for the rider on the ordinary saddle, and alsopermits a load to be placed on the carrier 5 for the purpose oftransportation. The back rest can be raised or lowered while the machineis in motion, by reaching back and throwing the lever 15. By loweringthe back rest the rider can jump on or off easily, which would bedifferent if the back rest were up.

The invention is not confined to the special forms shown, but is capableof modification in various respects within the scope thereof.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent is 1. An attachment for motor-cycles or thelike, comprising a support adapted to be fastened to the frame of thevehicle, a carrier frame mounted on said support, a seat hinged to saidframe and adapted to be swung up to form a back for the ordinary seat ofthe vehicle, and means to support said seat in raised position.

2. An attachment for motor-cycles or the like, comprising a supportadapted to be fastened to the frame of the vehicle, a seat hinged tosaid support and adapted to be swung up to form a back, and means tohold said seat in raised position.

3. An attachment for motor-cycles or the like, comprising a carrierframe adapted to be attached to the frame of the vehicle, over the rearwheel thereof, an auxiliary seat hinged at its front end to the carrierframe and adapted to be swung up to form a back for the ordinary seat ofthe cycle, and means to support the auxiliary seat in either raised orlowered position.

4:. An attachment for motor-cycles, or the like, comprising a supportingframe adapted to be fastened to the cycle, a carrier mounted on saidframe, a seat pivotally mounted at one end on said frame, and adapted tobe swung up or down over the carrier, and means including a spring toyieldingly support said seat in either position.

5. An attachment for motor-cycles or the like, comprising a supportingframe having uprights adapted to be attached to the rear part of thecycle frame, a carrier mounted on said support, for location over therear wheel of the cycle, a seat hinged at its front end to saidsupporting frame and adapted to be swung down to position over saidcarrier or swung up to form a back for the ordinary seat of the cycle,and means to hold the seat in either raised or lowered position.

6. An attachment for motor-cycles or the like, comprising a supportingframe having uprights adapted to be attached to the rear part of thecycle frame, a carrier mounted on said support, for location over therear wheel of the cycle, a seat hinged at its front 7 end to saidsupporting frame and adapted to be swung down to position over saidcarrier or swung up to form a back for the ordinary seat of the cycle,and means including spring arms to hold the seat in either raised orlowered position.

7. An attachment for motor-cycles or the like, comprising a supportingframe adapted for attachment to the frame of the cycle, a carriermounted on said frame, brackets projecting from said frame, a seathinged to said frame and adapted to swing up or down over the carrier,spring supports for the seat resting on said brackets when the seat islowered, and means to hold the seat in raised position when swung up.

In testimony whereof, I do affix my sig nature in presence of twowitnesses.
